Deke Slayton’s personal International Association of Turtles membership card, 3.25 x 2.25, issued on October 16, 1961. The notorious Turtles Club was a drinking club in which Wally Schirra held the title of a Grand Potentate. Slayton’s membership in the Turtles came up during Apollo 7, which was captured by the in-flight recorder. Reverse bears the printed instructions in giving the password for the club when asked, as well as the resulting penalty if unsuccessful: “you forfeit a beverage of his choice.” In very good condition, with card having been laminated, scattered wear, soiling, and toning, and surface loss to reverse.
